    摘要： A dual-fuel engine has a primary fuel supply and a secondary fuel supply, the primary and secondary fuels being arranged in use to mix with each other and with air for combustion in one or more cylinders of the engine. The supply of both the primary and secondary fuels is arranged to be actively managed in accordance with a desired engine performance characteristic by an electronic controller. In one arrangement the supply of a primary fuel is arranged to be actively reduced when a secondary fuel is supplied to the engine.

    摘要： A method for operating an internal combustion engine including extended operation in a homogeneous charge compression ignition mode at high loads includes operating the engine in the homogeneous charge compression ignition mode including spark-assisted ignition, monitoring an engine load, monitoring an engine speed, determining the engine to be in a high ringing range based upon the engine load and the engine speed, and when the engine load is in the high ringing range, operating the engine in a reduced ringing mode. The reduced ringing mode includes modulating a fuel injection timing according to a calibrated maximum combustion chamber cooling fuel injection timing, determining a preferred combustion phasing value, and modulating a spark timing based upon the modulated fuel injection timing and the preferred combustion phasing value.
